ANTIFOULING PROTECTION OF SPECIAL PARTS
METAL KEELS, FLAPS AND RUDDERS
Flaps and rudders made of steel or
alloys and other metal parts below
the waterline are areas of high
abrasion and wear.
You must carefully prepare the surfaces
(lead, cast iron or stainless
steel) to be painted using an abrasive
disc or by grit blasting to remove
all traces of old paint and
rust.
We recommend that you use the
two-pack system based on EPOXY
PRIMER (1 coat with a brush) and
AQUASTOP (3 coats with a short
pile roller) to attain a thickness of
600 microns. After the last coat
has been applied you must wait at
least 48-72 hours before continuing
the paint system with a coat
of ADHERGLASS or ADHERPOX
and then the antifouling as on the
rest of the hull.
Where necessary fill the keel
using EPOMAST PRO (on top of
EPOXY PRIMER). Then sand
and apply AQUASTOP.

STERN DRIVES
All boat motors are primed and stove-enamelled
by the manufacturer.
However they must also be treated
with a special antifouling product
to protect them against fouling.
If the stern-drive is in good condition,
wash the immersed part thoroughly
with DETERSIL and, after
sanding with fine abrasive paper,
apply:
• 1 coat of PROPELLER PRIMER
(with a brush)
• 2 coats of PROPELLER antifouling.
On the parts above the water:
• 2 coats of GEL GLOSS PRO finish.
If the stern-drive is in a poor condition,
you must strip it to the bare
metal by sanding or, where possible,
using an abrasive disc. Then it
should be protected using EPOXY
PRIMER (1 coat with a brush) and
AQUASTOP (3 coats with a short
pile roller or a brush).
Finish the system as for the submerged
parts.
PROPELLERS (bronze)
AND SHAFTS (stainless steel)
When treating propellers you must
be scrupulous, even fanatical,
about their cleaning and preparation.
If you apply a system which is
too thick, the profile, and therefore
the action, of the propeller will be
altered. Special products have
been developed which can be applied
in thinner layers and which
have high adhesion characteristics.
The entire system must be
renewed every season.
Follow the steps below:
• sand with coarse grade sandpaper,
scoring the surface;
• degrease with DETERSIL or
another degreasing detergent.
Repeat several times using a clean
sponge and rinsing with fresh water.
Do not use solvents which will not
eliminate the grease but simply
spread it around the surface. Be
careful not to smear the clean surface
or touch it with rags or fingers.
Any remaining traces of grease can
affect the adhesion of the product.
• Apply 1 coat of PROPELLER PRI-
MER and after 6-12 hours apply 2
coats of PROPELLER antifouling,
leaving 12 hours between each
coat. PROPELLER antifouling

PROPELLER
Antifouling for propellers, shafts
and stern-drives
CHARACTERISTICS
Antifouling formulated specifically
for the protection of
propellers, shafts, stern-drives,
flaps, etc. where highest
adhesion and abrasion
resistance is required. This
antifouling is copper and tin
free and therefore suitable
for all types of metal, providing
excellent adhesion and
good antifouling protection.
Must be used in combination
with Propeller Primer in
order to perform properly.
The new formulation has improved
resistance against
cathodic overprotection.

should only be applied on top of
PROPELLER PRIMER or on top of
a sanded layer of antifouling. Wait
at least 48 hours before launching.
Note: some alloys used for propellers
cannot be painted, due to
adhesion problems.
Do the PROPELLER first
When you are “doing” the hull,
paint the propeller first, not last.
This gives the PROPELLER hard
antifouling more time to dry completely.
